Not totally IN.[]
I'd forgotten to pick up a longbow grenade for this one. For laughs, I tried it anyway, with the sticky lobbed incendiary singularity mod I had. It landed on the lop of the pipe, next to the bottom light. I'd tossed it a little early; it opened after the singularity went off but before the explosion. While it was open, the grenade exploded, and I got the challenge. --Azaram (talk) 08:25, February 7, 2013 (UTC)
